kernel - Turn off zeroidle in the release branch.
* Turn of automatic page zeroing when idle in the release branch. This
code has been completely removed in the master branch. Pre-zeroing of
pages no longer has any benefit on modern cpus for a multitude of reasons.
* Will result in a small improvement in performance under heavy SMP loads.
